GenoTEX Benchmark Guide

Overview

GenoTEX is a benchmark for evaluating LLM-based agents on gene expression data analysis tasks. It provides curated datasets from GEO (Gene Expression Omnibus) with ground-truth analysis pipelines, testing agents on data preprocessing, differential expression, enrichment analysis, and biological interpretation. Published at MLCB 2025 as an oral presentation.

Running Evaluations

# Evaluate an agent on GenoTEX
from genotex import evaluate_agent

results = evaluate_agent(
    agent_fn=my_agent_function,
    tasks="all",            # or specific task IDs
    timeout_per_task=300,   # seconds
)

print(f"Tasks completed: {results.completed}/{results.total}")
print(f"Code correctness: {results.code_correct_rate:.1%}")
print(f"Statistical validity: {results.stats_valid_rate:.1%}")
print(f"Result accuracy: {results.accuracy:.3f}")
